The email subject line read like a party invitation: Our 30th Anniversary Celebration Plans. The attachment read like a ransom note. A color-coded spreadsheet listed two first-class tickets to Bali ($20,380), a used BMW X5 ($48,200), a $3,000 “overseas shopping card,” and—under a tab named Melissa’s House—Zillow links ranging from $250,000 to $320,000. At the bottom, a cheerful note from my mother: We deserve something special after 30 years. Don’t forget, your sister’s coming on the trip too. K
